I have quoted, Synops. Hemerob., p. 457, as belonging to Pamexis, a new species figured in Seba Thesaur., vol. iv., pl. 86, f. 20. The explanation says, “Color pallide subfuscus, maculis suture fuscis.” I can not here compare a colored copy of Seba's work, nevertheless the figure proves to be a male of a species of Pamexis without antennæ. The figures of insects in Seba are not good; but as the species belongs surely to Pamexis, and is larger than the other known species, and different from them, I wish to draw attention to the existence of a new species of this curious genus.

Yellowish, slender faintly villous; face yellow; between the antennae and a little above, a longitudinal median line, connected with a transversal one on the epistom, all black; palpi equal, pale, the apical joint of maxillary and this of labial, which is very little thickened in the basal half, somewhat brownish; antennae longer than head and prothorax, in the male fuscous annulated with luteous, especially before the tip, which is clavate; shorter, more clavate in female; the two basal joints brown, shining; vertex elevated, rounded, yellowish with two blackish dots; prothorax little longer than broad, yellowish, with two dorsal black lines, ending on the anterior transversal sulcus; sometimes a darker spot in front of the lines; on each side and nearly below a black band connected with the lateral one of the thorax; two black maculose bands including yellow spots on the thorax; two black maculose bands including yellow spots on the thorax; mesothorax before wings black, with yellow spots; abdomen of male much longer than wings, faintly villous yellow, with a fine black median line, apical part blackish, yellow on articulation and some lateral marks; appendages less than half the length of last segment, cylindrical, yellowish, brown at abse, densely clothed with black hairs; below and between them a small triangular yellow plate

6. Oligotoma Westwoodi , n. sp. O. Westwoodi Hag., Synops. Embid., p. 222 (no description, not named.) Length of body 4½ mill.; exp. of wings 7 mill. Male: As the specimen is enclosed in copal ( Gummi anime ), the colours are not certain, but the head, with antennae and palpi, the thorax and the legs in part, seem to have been blackish-fuscous; head more Raphidia-like than in any other species; more than half longer than broad; the rounded sides sloping down, the occiput less than half as broad as the front part with the eyes; head above slightly convex, epistom large, convex; eyes large, prominent, about orbicular, with a small excision for the insertion of the antennae; facets large, globose; antennae long, reaching the end of the metathorax, inserted in a longer socket, 15-jointed; 1st joint a little thicker, cylindrical, half as broad as long; 2nd as long as broad; all others obclavate, to three times longer than broad, but the 3rd to 5th a little shorter than the rest, the last one more ovoid, with tip rounded; there seems not to be wanting any joint more. Labrum large, rounded, a little darker in middle; max. palpi 5-jointed, the three basals alike, short, as broad as long; 4th a little longer,5th longer, ovoid; labial palpi 3-jointed, apical joint longer, ovoid.

Mr. H. W. Turner, U. S. Geol. Survey, San Francisco, Cal., has sent to me Phryganid cases from Mt. Conness, Mono Co., living in water at an altitude of over 10,500 feet. They are 15 m. m. long, the front half made by irregular small bits of stones, the apical half of short bits of pine leaves, and the case being narrower; around the case are placed longer parts of pine leaves or grasses in a herring-bone fashion. A few dry larvæ and the shape and arrangement of the cases show them to belong to the family of Limnophilidæ, and to the group of Hallisus.Other cases were collected from a small lake on the north side of Mt. Dana, at an altitude of over 11,500 ft. These cases are smaller, 10 m. m. long, of little bits of mica and other stones, more cylindrical, sloping a little to the end. They seem to belong to the family of Sericostomidæ, which is at least not contradicted by some remnants of dry larvæ.
